What to Do If AC Stops Working

Choosing the right air conditioner for your home is more than just picking the biggest unit within your budget. The right AC will efficiently cool your space, reduce energy bills, and ensure lasting comfort during hot months.

Consider Room Size and AC Capacity

Start by measuring your room to determine the required BTU (British Thermal Units) for your AC. A unit too small will struggle to cool, while an oversized unit will cycle on and off frequently, wasting energy and failing to control humidity properly.

For a small room (100-300 sq. ft.), a 5,000-7,000 BTU unit may suffice, while a larger living area (500+ sq. ft.) may need 12,000-18,000 BTUs. Consider window placement and sunlight exposure, as sunny rooms may need a slightly higher capacity.

Types of AC Units

Window ACs are cost-effective for single rooms, while split systems are ideal for multiple areas with quiet operation. If you want flexibility, a portable AC can move with you from room to room. For whole-home cooling, a central AC system is efficient but requires higher upfront investment and installation.

Energy Efficiency Matters

Look for AC units with a high EER (Energy Efficiency Ratio) or ENERGY STAR certification. Though they may cost more initially, they lower energy bills over time.

Additional Features to Look For

Features like programmable timers, sleep mode, and smart connectivity add convenience while improving efficiency. Check for washable filters for easy maintenance.

Conclusion

Choosing the right AC for your home ensures year-round comfort while saving energy and costs. Consult with a professional to determine the best AC type and size for your space to keep your home cool efficiently.
